DISH-WASHING MACHINE.

To all whom it may concern:

Be it known that I, ENGELBRIGHT A. Jo- HANSON, a. citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Dishashing Machines; and I do hereby declare the following to be a full, clear, and'exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to washing machines, and more particularly to a machine especially designed for washing dishes and the like.

The invention has for its object to provide a dish washing machine of novel and eflicient construction including a cylinder and a brush arranged therein, and means for independently or simultaneously rotating the brush-and cylinder.

With this and other objects inview, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which Figure 1 represents a perspective view, partly broken away, of the dish washing machine. -Fig. 2 represents a longitudinal sectional view through the machine. Fig. 3 represents a transverse sectional view on the line 33 of Fig. 2. Fig. 4: represents a fragmental perspective view of one of the cylinders removed. Fig. 5 represents a perspective view of one of the cylinder supports and holders removed. Fig. 6 represents a front elevation of the brush and holder removed, and Fig. 7 represents a perspective view of an article. holder removed.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 10 indicates a liquid container of suitable size and shape having a centrally disposed and transversely extending partition 11 therein dividing the container into two compartments or .chambers ment 12 is formed with an opening receiving a bushing or sleeve 14 in which is rotatably mounted a second sleeve 15, and a shaft 16 is rotatably mounted within the sleeve 15. The inner extremity of the sleeve 15 is preferably Specification of Letters Patent.

squared to fit within the correspondingly shaped central aperture formed ina circular piece 23 carrying a stub shaft 24 rotatably mounted in a bearing 25. The cylinder 18 is formed with a plurality of relatively small openings through which the water in the chamber 12 may flow and is also formed with a relativelylarge opening 26 through 1 which dishes or other articles are positioned withinor removed from the cylinder.

A hand crank 27 is removably secured to the outer. extremity of the shaft 16 and is formed with a longitudinal slot 28 in which is slidably mounted a key 29 having a knob 30 at one end whereby the key may be moved longitudinally with relation to the crank arm 27. An arm 31 is secured to the forward extremity of the rotatable sleeve 15 and is formed in its outer end with a recess 32 adapted to receive the key 29 when the hand crank 27 and arm 31 are moved into aline- I ment and the key is slipped inwardly within the slot 28.

A circular plate 34 is formed with a rectangular opening receiving the inner extremity of the shaft 15 and is provided upon the inner face with a pair of parallel flanges constituting'holders 35 for a brush 36 slidably mounted between the holders 35. A plate 37 is removably engaged against the front face of the strip 23 and carries a spring 38 extending longitudinally within the cylinder 18 and carrying a follower 39 at its forward extremity adapted to engage and retain plates or similar articles in operative engagement with the bristles of the brush 36.

When the key 29 is disengaged from the recess inthe extremity of the arm 31 rotational movement of the hand crank 27 is imparted to the brush 36 through the shaft 16 and plate 34, the brush rotating upon the tate the brush and the cylinder the arm 31 is moved into alinement with the hand crank 27 and the key 29 is slipped inwardly to engage Within the recess 32, thus locking the shaft 16 and the sleeve l5'against relative rotation. A shaft 42 is rotatably mounted lid in the front wall of the chamber 13 and removably supports a circular plate 43 at its rear extremity. The plate 43 is formed with a semi-circular flange identical with the flange 19 and supports a Washing and rinsing cylinder 44 having a strip 45 secured diametrically across its rear end and carrying a stub shaft 46 rotatably mounted in a suitable bearing member 47 secured to the rear wall of the container 10.

It will be understood that the rinsing and washing cylinder 44 may. he quickly and easily removed as. is the first mentioned cylinder 18. An opening is formed in each of the end walls of the chambers 12 and 13 and cocks 48 are secured in said openings for draining the water from the chambers.

.A pulley 49 is keyed upon'the forward extremity ofthe shaft 42, and a second pulley 50 is keyed to the sleeve 15, the pulleys 49 and 50 being connected by a belt 51, whereby rotational movement of the sleeve 15 is imparted to the shaft 42 and cylinder 44.

A plurality of radially disposed strips 52 are secured to the inner surface of the washing and rinsing cylinder 44 and are adapted to receive and hold cups and similar articles.

The type of article holder illustrated in detail in Fig. 7 is especially designed for containing small dishes, knives, forks, spoons, etc., and is adapted to be removably positioned within the rinsing cylinder 44. The holder 54 includes two substantially semi-circular end walls 55 and is formed with an opening 58 adapted to-he closed by a hinged door 59 preferably formed of wire mesh and hinged to on' of the longitudinal edges of the openings 58 at 60. A compartment 61 is formed in the holder 54 for-containing knives, forks and similar articles and the compartment is adapted to be closed by a hinged door 62 also formed of wire mesh.

What I claim is:

1. A washing machine including a liquid container, a cylinder rotatably mounted in .said container, and a brush rotatably mount intense inder, a brush rotatably mounted in said cylinder, and means for securing said brush for rotation with said cylinder.

4 A washing machine comprising a liquid containerfa-cylinder rotatably mounted in saidcontainer, means for rotating said cylinder, a brush rotatably mounted in said cylinder, and means connecting said crush with said cylinder rotating means.

5. A dish washing machine comprising a liquid container, a cylinder rotatably mounted in said container, a brush rotatably mounted in said container and projecting into said cylinder, and means for rotating said brush independently of said cylinder.
